Description

Technical Field

[0001] This utility model relates to the field of flange technology, and in particular to a high-pressure integrated flange. Background Technology

[0002] Flanges are key components connecting shafts, pipe ends, or equipment, achieving detachable sealing connections through a combination of bolts and gaskets. Their technical background mainly includes classification standards, connection methods, and sealing structures. Flange classification is primarily based on standards from chemical (HG), petrochemical (SH), machinery (JB), and national (GB) systems. Flange connections must meet the following technical requirements: 1. The sealing structure must use gaskets to prevent leakage; the sealing surface shape includes flat, concave, and raised face surfaces; 2. Bolt holes must be arranged across the center to avoid uneven stress caused by central placement; 3. Installation specifications require the two flanges to be parallel, and bolts to be tightened symmetrically to avoid forced tightening and tilting. Currently, the exhaust outlet space of reciprocating compressors is small, requiring a 90-degree fluid reversal and monitoring of temperature, pressure, and vibration. Furthermore, this area experiences high temperature, pressure, and vibration, making it prone to cracking and leakage when using ordinary flanges, and posing challenges to parameter monitoring. Therefore, those skilled in the art provide a high-pressure integrated flange to solve the problems mentioned in the background technology. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a high-pressure integrated flange.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A high-pressure integrated flange includes a flange plate, a 90-degree cavity inside the flange plate, a sealing groove on the surface of the flange plate, a sealing ring inside the sealing groove, a detection component adjacent to the sealing groove, and a buffer component inside the 90-degree cavity.

[0005] As a further embodiment of this utility model, positioning grooves are provided at the four corners of the flange surface, and bolts are installed inside the positioning grooves.

[0006] As a further embodiment of this utility model, reserved holes for monitoring are provided on both sides of the flange surface, and pressure and temperature sensors are installed inside the reserved holes.

[0007] As a further embodiment of this utility model, the flange has a mounting groove on its front side. The mounting groove is a reserved groove, and a vibration sensor is installed inside the mounting groove.

[0008] As a further embodiment of this utility model, the detection component includes a guide groove disposed adjacent to the sealing groove, a rubber ring disposed inside the guide groove, a flow guide hole disposed inside the guide groove, and an alarm sensor disposed at one end of the flow guide hole.

[0009] As a further embodiment of this utility model, the buffer assembly includes a mounting plate fixedly installed inside a 90-degree cavity. A vortex generator is fixedly installed on the surface of the mounting plate, and a plurality of guide plates arranged horizontally at equal intervals are provided on one side adjacent to the mounting plate inside the 90-degree cavity.

[0010] As a further embodiment of this utility model, the diameter of the guide plate is adapted to the inner diameter of the 90-degree cavity, and the large Liu plate is fixedly installed on both sides inside the 90-degree cavity.

[0011] As a further embodiment of this utility model, a water outlet is provided on the other side of the flange surface, and the surface of the water outlet is configured in the same way as the surface of the sealing groove.

[0012] The beneficial effects of this utility model are as follows: 1. The flange, 90-degree cavity, and sealing groove allow it to be used in pairs or individually. This flange is installed in the final stage exhaust of a reciprocating compressor or other fluid machinery to achieve a 90-degree deflection of the fluid and to monitor fluid temperature, pressure, vibration, or other parameters.

[0013] 2. By setting up detection and buffer components, the buffer component can guide the fluid to smoothly change direction, effectively break large-scale eddies, reduce flow resistance and turbulence, thereby significantly reducing fluid noise, vibration (pulsation) and energy loss. The detection component, together with the sealing groove, forms a double sealing barrier, realizing early leakage online monitoring and alarm, which greatly improves safety.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0017] Reference Figures 1-4 A high-pressure integrated flange includes a flange 1, a 90-degree cavity 2 inside the flange 1, a sealing groove 3 on the surface of the flange 1, a sealing ring 4 inside the sealing groove 3, a detection component 5 adjacent to the sealing groove 3, a buffer component 6 inside the 90-degree cavity 2, positioning grooves at the four corners of the flange 1, bolts inside the positioning grooves, reserved holes for monitoring on both sides of the flange 1, pressure and temperature sensors inside the reserved holes, and a mounting groove on the front of the flange 1, which is a reserved groove, where a vibration sensor is installed.

[0018] The flange features an integrated design, with fluid diversion and monitoring both implemented on the flange itself. Fluid flows into the flange through the inlet located on the opposite side, where an octagonal gasket and a pre-reserved sealing groove prevent leakage. The fluid flowing into the flange exits through outlets located below or above the flange, achieving a 90-degree diversion. Pressure and temperature sensors are installed to pre-reserved monitoring holes on both sides of the flange, using threaded connections for easy replacement and maintenance. A vibration sensor is mounted on the front of the flange and can be used in piston compressor heads and other fluid machinery requiring fluid diversion and monitoring within confined spaces. The integrated design allows for fluid diversion and monitoring on a single flange, saving space and cost. The structure is simple, component costs are low, production and processing are easy, and disassembly and maintenance are convenient and practical.

[0019] In this utility model, the detection component 5 includes a guide groove 51 disposed adjacent to the sealing groove 3, a rubber ring 52 disposed inside the guide groove 51, a flow guide hole disposed inside the guide groove 51, and an alarm sensor 53 disposed at one end of the flow guide hole.

[0020] In particular, when fluid leaks inside the sealing groove 3, it will fall into the guide groove 51. The guide hole inside the guide groove 51 will guide the fluid, and then the fluid will be transmitted to one end of the alarm sensor 53. After detecting the fluid, the alarm sensor 53 will issue an alarm, realizing early online monitoring and alarm of leakage, which greatly improves safety.

[0021] In this utility model, the buffer assembly 6 includes a mounting plate 61 fixedly installed inside the 90-degree cavity 2. A vortex generator 62 is fixedly installed on the surface of the mounting plate 61. Several guide plates 63 arranged horizontally and equidistantly are provided on one side of the mounting plate 61 inside the 90-degree cavity 2. The diameter of the guide plates 63 is adapted to the inner diameter of the 90-degree cavity 2. The large plate 63 is fixedly installed on both sides inside the 90-degree cavity 2. A water outlet is provided on the other side of the surface of the flange 1. The surface of the water outlet is the same as the surface of the sealing groove 3.

[0022] In particular, after the fluid enters the interior of the flange, it will flow through the 90-degree cavity 2. During the flow, the fluid will pass through the guide plate 63 and the vortex generator 62. The guide plate 63 and the vortex generator 62 are optimized by fluid dynamics CFD, which can guide the fluid to smoothly change direction, effectively break large-scale vortices, reduce flow resistance and turbulence, thereby significantly reducing fluid noise, vibration pulsation and energy loss.

[0023] Working principle: First, when the fluid inside the sealing groove 3 leaks, it will fall into the guide groove 51. The guide hole inside the guide groove 51 will guide the fluid. Then, the fluid will be transmitted to one end of the alarm sensor 53. After detecting the fluid, the alarm sensor 53 will issue an alarm, realizing early online monitoring and alarm of leakage, which greatly improves safety. After the fluid enters the inside of the flange, it will flow through the 90-degree cavity 2. During the flow, the fluid will pass through the guide plate 63 and the vortex generator 62. The guide plate 63 and the vortex generator 62 are optimized by fluid dynamics CFD, which can guide the fluid to smoothly change direction, effectively break large-scale vortices, reduce flow resistance and turbulence, thereby significantly reducing fluid noise, vibration pulsation and energy loss.

[0024] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described in detail here.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
